Logic Masters Deutschland e.V.

Normal sudoku rules apply. Standard German whisper, region sum line, Kropki dots (no negative constraint), and little killer rules apply. (To wit: Adjacent digits on a green whispers line must have a difference of five or greater. The digits along a blue region sum line must have the same sum in each 3x3 box entered by the line. Neighboring digits marked with a white Kropki dot are consecutive. Neighboring digits marked with a black Kropki dot have a 2 to 1 ratio. Not all dots are given. Numbers outside the grid indicate the sum of the digits on their indicated diagonal. Digits on these diagonals may repeat when otherwise allowed.) As always, comments welcome. Thanks!
